Well the service manual lists the following descriptions:
P0113: intake air temperature circuit high input (sensor 1)
P0223: throttle position sensor (sub) circuit high input
P1234: throttle position sensor (sub) plausibility
Now unfortunately I've just discovered part of my service manual is missing, so I only have the detail for PO113. Most likely causes:
- Intake air temp sensor failed
- Open intake air temp sensor circuit or connector damaged
- ECM failed
So... did you check that your mass airflow sensor is plugged in?
Also, check other plugs - it seems something might have come loose. Maybe even a plug on the ECU that all those sensors happen to run through.

Thanks Nick. I just did a quick visual in the parking lot and didn't see anything unplugged or obviously damaged. Do you think the increased airflow of the Red could have set it off, or does it definitely sound like a wiring issue?

The increased airflow would set off a different code. It shouldn't have triggered an excessive input on the temperature sensor.
The other thing is the throttle position sensor issues. I believe that would be the accelerator pedal position sensor, but I'm not positive. It could be the sensor for the actual throttle position. However, neither of those shares a plug with the IAT sensor. :-\

Does anyone know of someone around the area who could assemble the motor in my Evo? It's completely broken down and was ready for assembly, but the person I had doing it can't anymore. I have a number of aftermarket parts going on as well (internals, head, cams, turbo kit, ignition, AEM EMS, ect.) Just seeing if anyone can help me out.
